A method is presented for the preparation of thin (∼250 μm) porous stainless steel hollow fiber membranes based on dry–wet spinning of a particle-loaded polymer solution followed by heat treatment. Extraordinarily small radial dimensions were achieved by controlled shrinkage during thermal treatment. Above the glass transition temperature of the polymer, the dynamics of surface energy-driven viscous flow allow regulated reduction of the macrovoid volume, resulting in a substantial decrease in the final fiber diameter.
